Characterization of reinforced syntactic foams using ultrasonic

摘要

Non-destructive evaluation of defects like voids insyntactic foam reinforced with epoxy compatible chopped strandglass fibres, employing ultrasonic C-scan immersion throughtransmission method, was under-taken. The results showed that infour of the five similarly processed foam samples, the voids wereuniformly spread while in the fifth, which was processed by adifferent route, a large spread of low dense area was noticedemphasizing the influence that processing technique has on theamount of voids present in the composites.
